There are two graces in breathing:
drawing in air and discharging it.
The former constrains, the latter refreshes:
so marvelously is life mixed.
~ Johann Wolfgang von Goethe
The person who sits is more ready to bring forth clear things than someone who walks or stands. Sitting means peace. Thus we sit, which is bowing in humility among all creatures. Then the individual comes to a quiet peace reaching this peace in light. The light is given in the silence wherein one sits and dwells.
